Improvements in Apparatus for Drawing Ef-j fervescent Liquids, of which the following isV a specification. Y

This invention relates to improvements in apparatus for drawing off liquids which are retained under pressure without the excessive drawn ott directly under full pressure of the fountain.

The object of the invention 'is to provide such an apparatus of cheap and simple construction which is capable of being easily and quickly operated and which is adapted for drawing off carbonated beverages.

The invention consists of an apparatus for drawing off effervescent liquids comprising a pressure-relieving chamber, a socket for 'supporting said chamber, said socket being provided with a supply-channel, a dischargechannel, and a pressure-relieving channel, a

gas-escape pipe in the pressure-relieving chamber connected with the'pressurerelieving channel of the socket, a stop-cock below said socket composed of a casing and a spigot, said casing being provided with a supplypipe, a main spout, and an auxiliary spout and the spigot with a supply-channel, a dis`` charge-channel, and a "lf-shaped pressure-relieving channel, said channels serving to connect successively the supply-pipe with the pressure-relieving chamber and the latter with the main and auxiliary spouts, said casing being further provided with an interiorsemicircular groove opposite the pressure-relieving channel of the spigot and the spigot with a quadrantal groove connectingtwo adjacent ends of its T-shaped channel and stoppins on said socket and spigot for arresting the latter after making a half-turn in either l produced. Fig. 4- is a detail vertical longitudinal section through the stop-cock, showing it in position for discharging the liquid from the pressure-relieving chamber. Figs. 5 and 6 are vertical transverse sections ,through the stop-cock on lines 5 and 6 6, Fig. 4f, showing it in position for discharging the liquid from the chamber. Fig. 7 is a vertical longitudinal section through the stopcock, showing it in position for supplying effervescent liquid from the fountain to the pressure-relieving chamber; and Figs. 8 and 9 are vertical transverse sections through the stop-cock respectively on lines 8 8 and 9 9, Fig. 7.

Similar letters of reference indicate corresponding parts.

Referring to the drawings, A represents a pressure-relieving chamber, which is preferably made of glass of suitable thickness, so as to resist the pressure of the eiervescent liquid that is to be drawn off from the same. The neck of the pressure-relieving chamber A is screwed into a socket A', said socket being supported by a suitable pipe B, that is connected with the vessel or fountain containing the eifervescent liquid under pressure. A casing A2 is arranged at the lower part of the socket A and preferably' cast in one piece with the same. In the socket A `are arranged three vertical channels d cl2 cl3, which communicate, respectively, with rec- -tangularchannels ffzf3 in the spigot D ot' the stop-cock I). The middle portion of the spigot D is made conically tapering and tted tightly'intothe casing A2 and retained therein by a collar e, placed on a shoulder of the spigot, and a screw-nut e', screwed over the threaded end of the spigot. The opposite thicker end of the spigot D is provided with a handle D2 for permitting the turning of the spigotin its casing. In the thicker end of the spigot D', near the handle, are arranged two stop-pins e2, that are nearly diametrically opposite each other onthe spigot, said stoppins being adapted'to abut again'sta stationary pin e3 on the outside of the socket A.

The rectangular channel f of the spigot D is located in the same vertical plane as the channel d of the socket A and equal in diameter with said 'channel and the exterior diameter of the supply-pipe B. The second IOO rectangular channel f2 is arranged in the spigot D in the same vertical plane with the channel d2 of the socket A and a dischargespout D3, which is screwed into the front part of the casing A2, as shown clearly in Figs. l and 5. The third channel f3 is arranged in the spigot in a vertical plane with the channel d3 of the socket A and formed of a diametrical channel and a radial channel at right angles thereto, as shown in Figs. 6 and 9. This T-shaped channel f3 serves to connect the channel (Z5 with a smaller auxiliary spout D, which is located sidewse of the main spout D3 at the front part of the valve-casin g, as shown in Fig. 1. The channel d3 is connected at its upper end with a vertical escapepipe di, which extends to a suitable height into the pressure-relieving chamber A. The casing A2 of the stop-coclcD is provided with an interior semicircular groove f4, which extends from the inner end of the auxiliary spout D4 to the rear part of the casing A2, as shown in Figs. 6 and 9. The spigot D is further provided with a quadrantal groovef, which connects two adjacent openings of its diametrical and radial channels With each other. The ohannelsffz]3 in the spigot are so arranged relatively with each other, with the supply-pipe B, and with the channels in he socket A leading to the pressure-relieving chamber that by turning the spigot first in one direction and then back again toits former or normal position all the connections required for supplying the pressure-relieving chamber with effervescent liquid, permitting the escape of gas from the chamber to the atmosphere, letting in the air into the chamber, and then drawing off the liquid under atmospheric pressure from the chamber are produced.

The operation of my improved apparatus for drawing effervescent liquids is as follows: The spigot of the stop-cock D is turned from its normal position (shown in Fig. 2) into the position shown in Fig. S--that is to say, through an angle of nearly one hundredand eighty degrees-so that the second pin e2 strikes against the stop-pin es'on the socket A. This brings the angular channel f of the spigot in communication with the supplypipe B and with the channel d', leading to the pressure-relieving chamber A. The angular channelf2 is then in the position shown in dotted lines in Fig. 8, so as to shut 0H the communication of the pressure relieving chamber with the main spout D3. The channelf3 is likewise disconnected from the auxiliary spout D4, as shown in Fig. 9. The result is that the pressure-relieving chamber is filled With liquid under pressure, While the air in the chamber is compressed by the liquid rising in the chamber until an equilibrium of pressure in the fountain and in the pressurerelieving chamber is established. As soon as the pressure-relieving chamber is filled to this extent the spigot is turned by its handle in the opposite or return direction through an angle of one hundred and eighty degrees until the first pin e2 abuts again against the stoppin e3. During this motion the communication of lthe channel f with the supply-pipe B is interrupted and the auxiliary spout D4 placed bythe T-shaped channel f3 in connection with the channel d3 and the vertical tube d4, leading to the upper part of the pressurerelieving chamber, so that the compressed air and gas in the same are permitted to escapo. By continuing the return motion oi' the spigot the quadrant-al groove ofthe channel]t8 of the spigot D' moves along the semicircular groove of the valve-casing and permits the free escape of the compressed air and gas and the ingress of air until atmospheric pressure is established above the liquid in the pressure-relieving chamber, so that when the pin e2 of the spigot arrives at the stop-pin e3, in the position shown in Fig. 2, the connection of the pressu re-relievin g vessel A is established with the main spout D by the vertical channel cl2 of the socket A and channel f2, and thereby the discharge of the effervescent liquid from the pressure-relieving chamber by gravity at atmospheric pressure permitted. During the drawing off of the effervescent liquid from, the Inessure-relieving chamber the air is permitted to pass in through the auxiliary spout D4, angular channel f5, vertical channel-(Z3, and escape-pipe (Z4, so that the required vent is given to the interior of the pressure-relieving chamber, and thereby the free drawing off of the effervescent liquid into a tumbler or other vessel obtained. The object of the semicircular groove in the valve-casing and of the quad rantal groove in the spigot is to establish a permanent connection with the inside of the pressure relieving chamber and the atmosphere from the moment of relieving the chamber from pressure until the liquid is drawn, so that the gas may pass out and air go in, as required. As soon as the spigot is turned the connection of the pressure-relieving chamber A with the supply-pipe B is interrupted and in place thereof the connection with the auxiliary spout D4 established, the pressure of the air and gas in the pressure-relieving charnber being first relieved and, next, the connection of the interior of the pressure-relieving chamber with the atmosphere established. When it is desired to interrupt the discharge of the effervescent liquid from the pressure-relieving chamber, the valve-spigot is turned into an intermediate position, so that liquid can neither be supplied from the supply-pipe to the pressure-relieving chambernor discharged from said chamber through the spout. The operations of supplying the pressure-relieving chamber With effervescent liquid and of discharging the same from the pressure-relieving chamber are thus accomplished by two turning motions of the stopcock, the iirst motion (starting from the intermediate positiou referred to) serving for charging the pressure-relieving chamber with eifervescent liquid and the second or return IIO motion serving for disconnecting the pressurerelieving chamber from the supply-pipe and connecting it with the atmosphere and then also with the discharge-spout.

The simplicity of operation permits the handling of the apparatus by any one, so that the same can be used in connection with the ordinary fountains in Which carbonated liqnids are supplied, so that the excessive foaming which takes place, especially with rootbeer, sarsaparilla, or similar liquids, is obviated and still a greater percentage of carbonicacid gas retained in the liquid, for the sim ple reason that the liquid is first transferred into the pressure-relieving chamber under pressure, next relieved from pressure While in the same,an d,lastly, drawn olf under atmospheric pressure. y

When the apparatus is to be used for the dispensing of -etervescent liquids in connection with suit-able fruit-Syrups, it is preferable to make the vertical escape-tube in the pres-` claim as new and desire to secure by Letters Patentv.An apparatus for drawing off effervescent liquids, consisting of a pressure relieving chamber, a socket for supporting said chamber,said socket being provided with a supply-channel, a discharge-channel and a pressure-relieving channel, a gas-escape pipe iu the pressure -relieving chamber connected with the pressure-relieving channel of the socket, a stop-cock below said socket, composed of a casing and a spigot, said casing being provided with a supply-pipe, a main spout and an auxiliary spout and the spigot with a supply-channel, adischarge-channel and a T- shaped pressure-relieving channel, said channel serving to connect successively the supe ply-pipe with the pressure-relieving chamber and the latter with the main and auxiliary spouts, said casing being further provided With an interior semicircular groove opposite the pressure-relieving channel of the spigot, and the spigot with a quadrantal groove connecting two adjacent ends of its T-shaped channel, and stop-pins on said socket and spigot for arresting the latter after making a half-turn in either direction, substantially as set forth.

In testimony that I claim the foregoing as my invention I have signed my name in presence of two subscribing witnesses.
